JACOB I. I-IOVEY, OF ROCHESTER, NEW YORK.

CONNECTINGWROD.

SISPE IFICAIIN forming part of Letters Patent No. 307,651, dated November d, 1884'.

Application filed May E, 1884. (No model.)

'To all whom, t may concern;

Be it known `that I, JACOB I). Hover, of Rochester, in the county of Monroe, in the State ot New York, have invented certain Improvements in Connecting-Rods for Steam- Engines, ot' which the following is a specification, reference heilig had to the accompanying drawings.

My invention relates to certain im provements in the construction of the connectingrods of steam-engines, which :improvements are designed more particularly for use on the side or coupling rods of railway-locomotives, but are capable of being applied to other pnrposes.

My improvements are i'ully described in the following specification, and the novel features thereof specified in the claims annexed thereto.

My improved connecting-rod is represented in the accompanying drawings, in which Figure l is a side elevation. Fig. 2 `is a plan view. Fig. 3 represents onelof the longitudina-l bars ofmy improved connecting-rod. Fig. 4 is a view of one end of my improved connecting-rod on an enlarged scale. Fig. 5 is a partial side view o1" one of the bars on an enlarged scale. Fig; 6 is a cross-section representing a modiiication of the stays. Fig. 7 represents another modification of the same.

My improved connecting-rod is formed of two separate bars, A and B, each provided at the ends with two lugs, e e, the inclosed space or recess C between the lugs being iitted with the usual boxes or brasses, H H, Fig. 4. These boxes are secured in place by iianges projecting over the edges ot' the recess, and provision is made for taking up wear by means of the gib G held by a set-screw or any other ordinary or preferred means.

rlhe ends of my connecting-rod are secured together by the bolts F F provided with jamnnts. To prevent springing or bending, the rod may be stiffened by stays or struts I I, one or :more being usedaeeording to the length and material ot' the connecting-rod. These stays are composed ofthe block or collar L held in place by the bolt I and both the bars.

In place of the strut L the device repre`l passing through it sented in Fig. 7 may be used. A lug, L, on one or both bars of suoli height that when the bars are put together the edges will meet a bolt, I, passing through the bars and securing them rnily together. I i it isdesired to avoid weakening the connectingrod by the boltholes at these points, a stirrup or band, N, Fig. 6, may be passed around the bar, its ends passing through a clampingplate on the under side oi" the rod, and being threaded and provided with jam-nuts. In this ease the block or strut L is placed between the two bars, being provided with pins or other devices for holding it in place. The sides of the block L may be grooved to receive the stirrnp. i

In the practical construction of my improved connecting-rod the bars are forged all in one piece with enlarged ends and recesses therein' between the lugs c c, after which they are tinshed to shape and size by any suitable machinery. Il" it be desired to increase the section o1" the bar through the holes which receive the stays I, this may be accomplished by thickening` the bar at this point, as represented in Fig.

The obuious combination of lightness, strength, and stiffness in my improved bar will at once commend it to those acquainted with the state of the art as heretofore practiced, While the case of removing andreplacing the worn-out boxes is immediately evident. It is also clear that a great saving in metal, and consequently in cost, is effected by my improved construction.

Vil. The herein-described longitudinally divided connecting-rod, consisting of' the parallel oars A and B, having enlarged ends integral with the bars provided with recesses for the journal-bearings II I-I, and secured together by bolts F F, substantially as and for the purposes described.

2. rlhe herein-described longitudinally-divided connectingrod, consisting of the parallel bars A and B, having enlarged ends in` tegral with the bars, provided with recesses for thejourn al-bearings I-I H, secured together by bolts F F, and one or more intermediate omesi Stays, I, and struts,l L between the bars, snbby bolts F F at their enlarged ends and at or stantially as described. near the center of length by the strrup N and 3. The herein-described longitudinally-distrut L, substantially as described. vided connecting-rod, consisting 0f the paralyJACOB P. I-IOVEY. 5 1e1 bars A and B, having enlarged ends inte-` fitnessesz gral with the bars provided wthrecesses for GEO. B. SELDEN, -the journal-bearings H H, secured together H. G. PHILLIPS.
